Claws Mail 3.14.0 had been released as an update for multiple distribution
releases, including Fedora 25. It's just that the Fedora 25 update has
been stuck in the update-testing repository due to not getting enough
karma points from testers. Unlike the Fedora 24 update, which had entered
the stable updates repo in early October automatically.

So, some users may have come from an up-to-date Fedora 24 when doing the
distribution upgrade to the brand-new Fedora 25. Usually, it's a smart
idea to apply zero day updates and also any pending Test Updates.
Unfortunately, the users, who run into such a corner-case breakage during
a distribution, avoid the updates-testing repo like the plague.
